Pressure test the system. Any leak should show up under pressure. TBH if still installed = #1 place I'd look, connections on the reservoir, small nipple on the radiator, hose clamps, radiator cap (residue on overflow pipe would be a sign of that), and of coarse the reservoir itself at the seam.

 

Then get a pressure test kit and something under the car that would easily allow you to spot the liquid. Put flush / fill the system. Put 20psi of pressure and leave for a few hours...

 

Coolant dye and a UV light will help you find the leak pretty quickly.

 

Just because it looks okay doesn't mean that it's working properly.

 

UPDATE

Today I checked and there was significant fluid loss in the Reservoir from yesterday I will attach a picture and point to where I filled up to yesterday and where it’s at today. I am guessing this is overflow because the tip of the overflow tube was wet

aside from that I found three tubes that go out from the Reservoir I checked the connections and follow the one leading up to the mamifold.
And I did not see any dampness. I did run the car for 15 minutes at idle here is what I did notice however As the engine gets hotter the fluid level in the reservoir goes up. Also if I rev the motor at idle the temperature of the car actually drops..

is this normal?

I had purchased a lower temperature thermostat over the winter and I was going to get it installed with. Mechanic. I suppose I can get the mechanic to have a look at it when he installs the new thermostat

 

do you mean that there is fluid possibly leaking from the cap?

 

I see what appears to be white/pinkish looking deposits on the valve cover directly under the TBH plate = sign when it's leaking and then boiling/evaporating (hence why I hate them!!!!). I also see pink/reddish goo on the left hose on the TBH. If you want to find actual leaks quickly and easily without it burning off or not being able to probe due to the engine running pressurize the system to 20PSI watch the gauge and the look all over the place to leaks and then look on the ground for any fresh coolant. Without doing that you're honestly chasing your tail.

 

sorry what is tbh plate?
